Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“In 2017 I purchased a recreational vehicle with a dodge chassis with the attached VIN. It currently has about 4500 miles on it. From the very beginning I have had problems with the transmission down shifting when traveling at highway speeds (55 to 65 MPH) which pegs the tach (7000 plus). This would occur when traveling up slight grades while on cruise control and would happen at random intervals (roughly 200 miles) without warning. I have been to the dodge dealer and discussed the problem with them. …”

“2015 Ram Promaster city currently has 715 miles on the odometer. We have owned this vehicle for 3 months, and purchased it new. The problem I'm about to describe has occurred on four (4) separate occasions in the last 3 months. While vehicle is in motion, (has occurred between 25 MPH and 75 MPH) the transmission clunks loudly, and is met with a sudden loss of engine power. Each occurrence forced us to pull vehicle to side of road, (3 occurrences on city streets, 1 occurrence on freeway) turn the engine/ignition off, and start engine again. …”

“Several incidents when accelerating, the engine goes into a limp mode, followed by indicator lights coming on P0401, P0299, P226C. The vehicle will not accelerate and travels at a max speed of about 5mph. This has happened in traffic every time and has put me and my family, as well as other vehicles, at extreme risk of being in an accident, not being able to accelerate out of the way of oncoming traffic. After several cycles of turning the vehicle off and on, it returns to normal function. The vehicle has been inspected at a Dodge Service station. …”

“This is new model for dodge in 2015 and comes equipped with the zf 9-speed transmission. At the lower end, the van lacks acceleration for passing or needed acceleration especially after deceleration. After reading the complaints about the zf transmission in the cherokee, the descriptions noted are exactly what is happening to my van. This is extremely concerning when on a freeway and once I slow down and then have to speed up fast, there is a delay or lull in the acceleration.”
